Available in a large variety of sizes and lengths

These high-quality, close tolerance, CNC-machined 304 stainless steel fittings are highly resistant to corroding, pitting and discoloring. Another benefit is that they make installation and removal of the fittings easy every time. They're available in many lengths and sizes. The heater hose fittings come with either a hex or a 12-point, while the stainless steel pipe plugs come with an inverted Allen hex, or an external 12-point or hex head. These are the best hose nipples and pipe plugs you can get anywhere.
